I want to become breatharian

Hello,
I am 13 y.o., and i want to become a breatharian. I wonder if i am going to continue growing while living on air alone, or if I am going to stay the same height like now, I am just 153cm.
i also wonder if I am going to get my cyclus while I am breatharian? Do breatharians drink water? What about drinking tea? If i don't drink water, can I have my menstruation? Can breatharians become pregnant and have kids?
Can breatharians sweat? I heard that people sweat when they make love. What happens to our intestines, if we stop eating for many years? If we don't drink, do we urinate?
What if a 7 year old child becomes a breatharian, will he continue growing? (my brother)
Thanks
